| Abstract: | Under a fixed precision, how to get the solution of the cauchy problem of heat conduct equation at any point (t,x)? A kind of approximating method that use polynomial and Fourier series has been given in this paper. At final, this method has been improved to solve the solution that satisfy the fixed precision in any bounded domain. |
